    Need to know the following based on the information above please show work:

    • His relative oxygen consumption when walking.
    The formula for oxygen consumption is ( speed m/min ) x ( 0.2 ml/kg/ min per m/ min) + 3.5 ml/ kg/ min
    3 mile/ hr X 1 m/0000621 mile X 1 hr/60 min = 80.51 m/ min
    O2 consumption = 80.51 m ...

    Solution Summary

    A breakdown of a metabolic plan for a hypothetical patient. Oxygen consumption is the best indicator of person's level of aerobic fitness. It is affected by age, gender,and body size.
